The Japan Aerospace Exploration Agency, JAXA (formerly National Aerospace Laboratory of Japan, NAL) has been studying the possibility of remote medical treatment using communication satellites. To transmit stable, high-bit-rate movies and precise images of a patient from an ambulance via satellite during transportation to a medical center, a high satellite elevation angle is required in order to avoid shadowing from high buildings. A number of satellite constellations can be proposed for such a system, consisting of three or more satellites. In this paper, several types of orbits such as 24-hour orbits, figure-eight orbits, Tundra orbits, 16-hour orbits, 12-hour orbits, Molniya orbits, or other interesting orbits are compared by considering coverage duration, the required number of satellites, perturbations, link budgets, launch costs, and so on.
